What if we want to suggest you add e-books that aren’t coming up as options to suggest? I’m looking for an author named Shahida Arabi, self-help/growth type books. Are they unable to be added?
Currently, there is no way to ask for recommendations on the new Libby app, though that may change in the future, since that used to be an option in the old Overdrive app. Also, I did notice that her books are self-published using CreateSpace, which means it is less likely that it would be available via either Libby or Axis 360 in any case.
I’m using the Overdrive app through Amazon on my fire tablet. I’ll look into other means of getting her books. Thanks very much!
You should be aware, Karen, that the Overdrive app is bring replaced by one called Libby. Overdirve will work for now, but to be on the safe side, you should download the new app as soon as you get a chance. You can find more info about here here https://meet.libbyapp.com/
Am I able to use two paper whites at the same time so I can read the same book in two different locations?
I believe you can. To read more, refer to the Amazon site. https://www.amazon.com/gp/help/customer/display.html?nodeId=201241870
William, I will look into the matter and get back to you.
